Plotline

When Voyager contacts Icheb's home planet Janeway decides that it is time for the boy to go home. Icheb, who has developed a strong interest in astronomy, is reluctant to return to a world on which repeated Borg attacks have left little technology. Seven is also reluctant to lose her favourite student, but Janeway is adamant and eventually Icheb agrees to return home. Unfortunately, Seven discovers evidence that Icheb's parents have been lying in order to conceal a secret which threatens the boy's life - and brings Voyager face to face with the Borg.
